Siemens is committed to ultra-fast, bidirectional and flexible charging in electric buses and trucks
Siemens will test this new charging system in electric trucks and buses by reusing old vehicles, at the Charging and Validation Test Center of the Dutch company VDL. Second-life batteries will also be used in the storage system, to be able to reuse the battery from the old electric buses.
Siemens and VDL Bus & Coach have joined forces to develop new flexible, bidirectional and efficient charging infrastructures, capable of working in the most extreme demand conditions, just as a combustion vehicle would do. It is an innovative work focused on the installation of modular fast charging systems, mixed with stationary battery storage systems and also a system organized by an energy management application, offering bidirectional charging between cars and the grid.
This system includes V2G (vehicle to network) functions to perform bidirectional charging, to recharge the buses' batteries and also so that they can introduce energy into the network.
Great loading speed
It is a power management application that works with a special switching matrix that allows you to flexibly mix the capacity of charging stations. It runs on MindSphere, the IoT operating system, which is open and cloud-based from Siemens.
Siemens has installed three fast charging stations with 150 kW power. The charging speed is regulated flexibly through the electronics that are implemented in them. They are stations that can be interconnected temporarily, to charge three vehicles in parallel, at 150 kW each, or a single vehicle to reach a power of up to 450 kW.
The V2G function included in one of the stations allows it to communicate with the network and provide power, when there is not enough capacity. This means that they can not only get energy from the grid and the storage system, but they can also return it. This function helps manage the network and allows peaks in energy demand to be covered.
When you bring together a storage system, energy management application and charging stations, the total capacity can be readjusted according to current and future needs. It is a pilot project that aims to demonstrate the great flexibility of the system and provide the necessary information for the electrification of transportation.
Electric mobility represents a fantastic way to bet on sustainable mobility, which aims to focus on clean vehicles and transport that do not emit polluting gases to the planet or pedestrians.
The electric vehicle is becoming the most efficient option for the majority of users, who see this option as a way to enjoy driving in a safe and sustainable way.
